摘　　要：目的:探讨Tei指数检测不同程度冠状动脉病变患者右心功能变化的临床应用价值。方法:采用组织多普勒显像技术对30例正常对照组、30例冠状动脉造影阴性组(狭窄<50%)、30例轻度冠状动脉狭窄组(狭窄50%～74%),30例中度冠状动脉病变组(75%～94%)进行三尖瓣环右室室间隔及游离壁Tei指数测定。结果:冠状动脉造影阴性组Tei指数与正常对照组比较不存在显著差异,轻度冠状动脉狭窄组及中度冠状动脉狭窄组Tei指数显著高于正常对照组(P<0.05)。结论:冠状动脉病变患者右心功能亦受损,Tei指数能用于评价右心功能受损情况。Objective To assess the clinical value of inspecting the changes of right ventricular function in patient with different extent coronary arteriosclerosis by TDI Tel index. Methods The tricuspid annulus of right ventricular septum and free wall Tel index were determined by tissue Doppler imaging （TDI） technique in the 30 normal subjects, 30 patients with negative results of coronary arteriongraphy （stenosis %50 ）, 30 patients with mildly coronary stenosis （stenosis 50 - 74 % ）, and 30 patients with moderate coronary stenosis （stenosis 75 %- 94 % ）. Results： The right ventricular Tel index in mildly and moderate coronary stenosis patient was obviously higher than that in the normal subject （ P 〈0.05）, but there was no statistic significance in the difference between normal subject and patient with negative results of coronary arteriongraphy. Conclusion：Coronary stenosis has impact on right ventricular function change and the Tel index can be used to estimate the right ventricular function.
